There is no way on Forum front-end > My Profile > Account page, but there should be way in Dashboard > Users > Edit Profile admin page (if the Moderator has appropriate Wordpress User Role to access Dashboard > Users admin page).

I have a forum on my page where only the "coach" group can post.  I assign it manually now, but fear once I assign MOD to certain users.  They will have access to the backend, they will see or be able to modify the site, theme, or other settings I really dont want them to even see.

It would be great for some type of front end tool, OR dashboard access where the only viewable backend is what the Mod has access to (changing user role).
